Abstract: In a real-time distributed control system in which a plurality of network controllers are connected, a middleware module in each control unit executes starting of application modules and calling RT communication processing according to starting order information in application configuration information. RT communication service sends and receives messages between the application modules corresponding to the calling. The application configuration information and the messages are generated by an information processor based on user defined information, and transmitted to each of the units. A network driver executes network communication using a network controller which stores sending and receiving messages. A network driver priority manager determines priority of processing of the network driver corresponding to priorities of sent and received messages, and a scheduler executes processing of the network driver according to the priority of the processing of the network driver.

Abstract: Secure access to internal data resources is facilitated through a gateway CGI on an internet visible computer system with an internet visible web server configured by rules to forward calls to the gateway CGI. The gateway CGI packages information from the call to send by secure socket connection to a server-like access control program on a secure host system which can reconstitute the call if authenticated and/or validated and serve the request, returning the sought after data or resource through an encrypted channel if desired. Variations for high throughput environments and operation with application program session controllers are described.

Abstract: An apparatus and method for determining a program neighborhood of a client node in a client-server network is described. The program neighborhood of the client node includes application programs hosted by application servers on the network. The present invention enables a user of a client node to learn of these application programs. The user is not required to know where to find such applications or to manually establish links to such applications. To make the client node aware of its program neighborhood, a host server collects application-related information corresponding to application programs hosted by the servers in the network. The application-related information can include the application name, the server location of the application, minimum capabilities required of client nodes for executing the application, and those users who are authorized to use that application. User credentials are received from the client system. The user credentials are used to filter the application-related information.

Abstract: A data communication switch receives packets having first priorities, generates second priorities as a function of the first priorities, prioritizes selected ones of the plurality of packets as a function of the second priorities and transmits the plurality of packets having the second priorities. The first priorities may be inbound Std. 802.1Q tag priorities and the second priorities may be regenerated Std. 802.1Q tag priorities. Priority selection may be communicated in the switch through the expedient of packet marking. Marks may be instantiated in the packets prior to subjecting the packets to prioritization on the switch and removed from the packets prior to transmitting the packets from the switch. The switch may be arranged to prioritize selected ones of 802.1Q-complaint tagged packets based on a tag priority while preserving tag priority signaling for all such tagged packets.

Abstract: A unified web-based voice messaging system provides voice application control between a web browser and an application server via an hypertext transport protocol (HTTP) connection on an Internet Protocol (IP) network. The application server, configured for executing a voice application defined by XML documents, selects an XML document for execution of a corresponding voice application operation based on a determined presence of a user-specific XML document that specifies the corresponding voice application operation. The application server, upon receiving a voice application operation request from a browser serving a user, determines whether a personalized, user specific XML document exists for the user and for the corresponding voice application operation.

Abstract: Automatic compilation of address filter information that permits a cable modem to appropriately route incoming data packets to destination devices is described. Cable modems use address filter information to identify incoming data packets that are addressed to communication devices associated with the cable modem. The address filter information might be, for example, a list of addresses of communication devices that have previously registered with the cable modem. On occasion, the cable modem may have incorrect or insufficient or incomplete filter information when, for instance, a new communication device is added to a group of networked communication devices associated with the cable modem. In order to automatically recognize associated communication devices that are to be registered with the cable modem, a cable modem driver inspects the source address of outgoing data packets.

Abstract: A method and system is provided for caching client management data in a capacity planner. Client management data is collected and cached over a selected time period.

Abstract: A mechanism for identifying link failures in a network is disclosed. To identifying link failures, a failed-link discovery mechanism receives information that represents a physical topology of the network. A management station that is associated with the network is identified and a path between one or more devices of the network and the management station is determined. For each link, a set of beyond link devices, that identifies only those devices that are beyond a particular link relative to the management station, is identified. Thereafter, a first message is sent to each active device within the network. Based on the responses that are returned in response to the first messages, a set of non-responding devices within the network is determined. The set of non-responding devices is then compared to each set of beyond link devices to identify link failures within the network.
